How to play
Each row and each column carries a regex clue. Drop letters from a small alphabet into the grid so every line matches its pattern. A live matcher recolors each clue as you type, green when the line matches, amber while it is still satisfiable, red when no completion can work.
Click a cell, then type or tap a letter from the alphabet pad
Selected row and column clues are shown in the clue bar
